The Detroit Tigers lost a fan favorite in Curtis Granderson this week, but gained a fan in former NFL guard Mark Schlereth.

Schlereth, the father of newly-acquired Tigers reliever Daniel Schlereth, officially switched his allegiance from the Diamondbacks to the Tigers following Detroit’s three-way trade Wednesday.

Daniel, 23, was drafted No. 26 overall in the 2008 draft by the D'backs before being traded to the Tigers, along with teammate Max Scherzer.

“On this day, I would like to decree that I am no longer and Arizona Diamondbacks fan,” Schlereth said Thursday on Mike & Mike in the Morning on ESPN Radio. “Now, I have become a Detroit Tigers fan. Long live the Detroit Tigers and the old English 'D'.”

Schlereth was presented a Detroit Tigers cap and the ESPN football analyst professed his allegiance by replacing his D’backs cap with the Tigers hat.
